Definitions
- the invention relates to new polyol emulsions of castor oil and monoepoxides and polymer cements prepared therefrom together with methylenediphenyl diisocyanate (MDI) and cement.
- MDI methylenediphenyl diisocyanate
- JP 2001-302304 and JP 2004067463 describe polyol emulsions of castor oil and the reaction products of ricinoleic acid with monoepoxides.
- the viscosity of these emulsions is lower than that of pure castor oil emulsions, but the preparation of the ricinoleic acid monoepoxide adducts requires an additional reaction step.
- the ricinoleic monoepoxide adducts still contain OH groups which are capable of forming hydrogen bonds and thereby increase the viscosity.
- Desirable therefore emulsions of castor oil and a reactive diluent, which contains no OH groups, but under the basic reaction conditions of the polymer cement formation free OH groups, which then react to crosslink with the MDI.
- low-viscosity emulsions having the desired properties can be prepared from castor oil and monoepoxides, which can be reacted with MDI and cement to form polymer cements.
- the monoepoxide reacts under the reaction conditions of the formation of the polymer cement with ring opening to the corresponding glycol and thus provides the required OH groups.
- the invention therefore comprises emulsions containing
- auxiliaries and additives 0.5 to 5 parts by weight of auxiliaries and additives.
- Ricinusöl within the meaning of the invention are esters of glycerol with ricinoleic acid, wherein on average at least two of the OH groups of glycerol are esterified with ricinoleic acid. Both technical and pharmaceutical qualities can be used.
- Monoepoxides in the context of the invention are all compounds having one epoxy group per molecule. Preferred monoepoxides correspond to the general formulas (I) to (IV),
- R is a C4 to C8 alkyl radical or a tri (m) ethoxysilylpropyl radical
- R ' is hydrogen, a C 1 to C 4 alkyl radical or a vinyl group.
- auxiliaries and additives may be, for example, nonionic emulsifiers, defoamers and thickeners, which are contained in a preferred embodiment as auxiliaries and additives in the emulsions according to the invention.
- nonionic emulsifiers ethoxylated fatty alcohols or alkylphenols, fatty acid esters of polyethylene oxides, fatty acid esters of sorbitan or ethoxylated sorbitan, block copolyethers of polyethylene oxide with other polyepoxides, preferably polypropylene oxide, ethoxylated fatty amines or fatty amides or glycosides or esters of
- Sugars are used. It is also possible to use mixtures of nonionic emulsifiers, the HLB value of the total mixture being from 8 to 19, preferably from 10 to 14.
- defoamers e.g. Silicones, silicones containing ether groups, hydrophobized silicic acids, nonionic emulsifiers having an HLB value of from 3 to 10, or mineral oils can be used.
- Nonionic emulsifiers based on sorbitan esters or mineral oils are preferably used.
- Cellulosic derivatives such as hydroxyethyl, methyl, hydroxypropyl or carboxymethyl ethers can be used as thickeners. It is also possible to use thickeners based on polyurethane or polyurea, inorganic sols, such as aluminum hydroxide, polyvinyl alcohols, polyvinylpyrrolidones or (co) polymers of (meth) acrylic acid or of (meth) acrylamide. Acid-functional polymers are preferably used in the form of their alkali metal or ammonium salts
- Preferred thickeners are cellulose derivatives of the abovementioned type, more preferably hydroxyethylcellulose.
- the emulsions according to the invention may additionally contain polyols, such as glycerol, oligomeric glycerols, trimethylolethane, triethylolpropane, sugar alcohols, sugars, sugar derivatives or alkoxylated amines, such as triethanolamine or propoxylated ethylenediamine.
- polyols such as glycerol, oligomeric glycerols, trimethylolethane, triethylolpropane, sugar alcohols, sugars, sugar derivatives or alkoxylated amines, such as triethanolamine or propoxylated ethylenediamine.
- the amines can be neutralized with carboxylic acids or hydroxycarboxylic acids, such as citric or tartaric acid.
- the viscosities of the emulsions according to the invention are typically 50 to 5000 mPas, preferably 90 to 300 mPas at 23 ° C.
- the emulsions contain as auxiliary substances or additives preferably 1 to 3 parts by weight of sorbitan monolaurate as emulsifiers and defoamers, whereby in addition a better water resistance of the polymer cements is achieved, determined by "bleaching" caused by stagnant water (visual comparison).
- hydroxyalkyl derivatives of cellulose are particularly suitable as thickeners.
- auxiliaries and additives which contain isocyanate-reactive groups, such as OH or NH groups, are preferred.
- at least 1 part by weight of an ester of sorbitan, at least 0.5 part by weight of ethoxylated fatty alcohols and at least 0.1 part by weight of hydroxyethylcellulose are included as auxiliaries and additives.
- the emulsions according to the invention are prepared by mixing the components while shearing with stirrers or jet dispersants, wherein preferably the fat-soluble components in the castor oil and the water-soluble components in the water are pre-dissolved. It is irrelevant whether the aqueous phase is metered to the oil phase or vice versa.
- Another object of the invention are polymer cements containing
- the known phosgenation products of the condensates of aniline with formaldehyde can be used as MDI (methylene diphenyl diisocyanate).
- MDI methylene diphenyl diisocyanate
- these may be both the monomeric MDI isomers having two aromatic 6-rings per molecule and the higher molecular weight MDI types containing three or more aromatic 6-rings per molecule.
- Cements within the meaning of the invention are hydraulic binders which are composed of inorganic, non-metallic, finely divided substances which harden independently with water and remain solid in air or in water, for example Portland cements, calcium aluminum cements, calcium sulfate cements, hydrated calcium oxides, magnesium oxichloride - Cements and their mixtures with calcium hydroxide, magnesium hydroxide, pigments or sand.
- Portland cements calcium aluminum cements, calcium sulfate cements, hydrated calcium oxides, magnesium oxichloride - Cements and their mixtures with calcium hydroxide, magnesium hydroxide, pigments or sand.
- cements such as, for example, Portland cements, iron Portland cements, blast furnace cements, road blocks, trassized cements, oil shale cements or alumina cements, which are at least 23 Wt .-% CaO, preferably at least 50 wt .-% CaO.
- the cement mixtures used according to the invention contain 1 to 10 wt .-% calcium hydroxide (slaked lime).
- the preparation of the polymer cements according to the invention is carried out by mixing the components under shear, wherein preferably the emulsion is initially introduced and then MDI and
- cement can be added. After admixture of the MDI, the mixture undergoes a viscosity maximum by reversing the emulsion from an oil in water to a water in oil emulsion. The mixture typically cures after a pot life of 8 to 45 minutes to form a non-foamed polyurethane filled with cement.
- the inventive polymer cements cure at temperatures from 0 0 C to 40 0 C at any
- the application can be done by trowelling or pouring. During curing, by rolling a spiked roller, the escape of carbon dioxide formed from the isocyanate-water reaction can be facilitated.
- Ricinus oil 1 DIN 55939 was used in the examples.
- the viscosity was measured according to DIN EN ISO 3219 / A3 at a shear rate of 240 l / s and 23 ° C

- Example 2 The procedure was as described in Example 1, wherein Polypox R24 was replaced by the same amount of Ruetapox EPD HD. This gave an emulsion which remained stable after 30d at room temperature, after 30d at 50 ° C at a filling height of 5.5 cm an aqueous phase of 0.1 cm height saying goodbye and remained stable after 30d at 4 ° C.
- the viscosity was 210 mPas at 23 ° C.
- Example 2 The procedure was as described in Example 1, wherein Polypox R24 was replaced by the same amount of n-butyl benzyl phthalate. This gave an emulsion which remained stable after 30d at room temperature, after 30d at 50 0 C and after 30d at 3 ° C. The viscosity was 190 mPas at 23 ° C. - -
